Definitions

  • the present invention refers to a process for feeding individual sheeted products to a conveyor with thrusters in an apparatus for packaging publishing products and to a feeder that uses such a process.
  • the purpose of the present invention is therefore that of solving such problems, carrying out a feeding of sheeted products towards a conveyor with thrusters, in particular for example associated with a packaging apparatus, which is always perfectly neat and correct.
  • Another purpose is that of being able to carry out feeding of sheeted products towards a conveyor with thrusters, irrespective of the operating speed of the entire packaging apparatus of the products.
  • FIG. 1 is a side elevation partial section view of a controlled supply feeder according to the present invention that is transferring the sheeted product on a conveyor with thrusters, shown only partially, and
  • FIG. 2 is a diagram that shows the variations in feeding speed of the sheeted product with respect to the speed of the conveyor with thrusters in an entire discharge cycle, at three different operating speeds of the machine.
  • FIG. 1 in general, a feeder or rather a feeding device 11 of individual sheeted products is shown schematically, through which individual sheeted products 10 are withdrawn from the bottom of a pile 12 and are fed towards a conveyor 13 with thrusters 14 , in particular associated with a packaging apparatus (not shown).
  • the sheeted products 10 are piled up and held by vertical guides 15 , which, through suckers 16 lying below (just one of which is shown), allow the last sheeted product 10 at the base of the pile 12 to be picked up and slipped away. In this way an end edge of the sheeted product 10 is slipped away from the bottom of the pile 12 and is gripped by a suitable gripping element arranged integral with a rotating disc that is the actual feeding device towards the conveyor with thrusters.
  • the suckers 16 are arranged on a rocker arm 17 and the gripping element is a pincer 18 associated with a suitable rotating pincer-holding disc 19 .
  • a band 20 is foreseen that partially winds around the pincer-holding disc 19 and that collaborates to hold the sheeted product 10 in position integral with the pincer-holding disc 19 , before being released towards the conveyor 13 with thrusters 14 .
  • rollers 21 are both connected through a suitable belt transmission 22 to a variable speed motor 23 that is commanded to rotate according to the operating speed of the packaging apparatus.
  • the invention foresees that there is a special process for feeding individual sheeted products 10 to a conveyor 13 with thrusters 14 in a packaging apparatus, for example of publishing products such as newspapers, magazines, books, envelopes, giveaways or other similar products.
  • Such feeding is carried out according to the particular requirement of the packaging apparatus.
  • the process is characterised in that the rollers 21 are actuated at a different speed to that at which the conveyor 13 with thrusters 14 advances and to the peripheral speed of the pincer-holding disc 19 in at least a portion of a discharge cycle K of the individual sheeted product 10 .
  • This process is actuated when the speed of the packaging machine is a different speed to the optimal operating speed.
  • the rollers 21 of the feeder or feeding device 11 which had a peripheral speed equal to that of the conveyor 13 with thrusters 14 and the pincer-holding disc 19 from 1 ⁇ 8 to 4/8 (indicated with solid line), carry out a great acceleration according to a first half of a certain curve A (in a solid line) reaching a correct release speed of the product V rpl . In such a way they quickly actuate the discharge of the individual sheeted product 10 in the second half of the discharge cycle K for feeding to the conveyor 13 with thrusters 14 .
  • the motor 23 accelerates greatly determining a great acceleration of the two rollers 21 and carrying out a quick positioning of the individual sheeted product 10 in front of the thruster 14 in arrival.
  • the rollers 21 actuate a lower acceleration according to a curve B again to reach a correct release speed V rp2 of the individual sheeted product 10 in the same step between 4/8 and 6/8 of the discharge cycle K to the conveyor 13 with thrusters 14 . Then, having discharged the product 10 on the conveyor, also in this case the rollers 21 decelerate with a second symmetrical half of curve B 1 until it goes to the same speed as the conveyors with thrusters and the rotating pincer-holding disc.
  • the graph then also illustrates an example in which the packager and consequently the conveyor 13 with thrusters 14 and the pincer-holding disc 19 have a constant average operating speed V med , and the rollers 21 of the feeder 11 rotate at an optimal product release speed V orp , a speed that is thus maintained when the general working conditions do not change, as indicated by the straight line C, C 1 .
  • the two further examples shown in the graph propose different operating situations in which the operating speeds of the packaging machine and therefore of the conveyor 13 with thrusters 14 and of the pincer-holding disc 19 are higher than the average speed.
  • the packager or packaging apparatus and consequently the conveyor 13 with thrusters 14 and the pincer-holding disc 19 have a higher operating speed than the constant average one V 3 , and the rollers 21 , which have a peripheral speed equal to that of the conveyor 13 with thrusters 14 and the pincer-holding disc 19 from 1 ⁇ 8 to 4/8, actuate a certain deceleration according to a first half of a certain curve D reaching a correct product release speed V rp3 . Then once the product 10 has been released, the rollers 21 accelerate once again with a second symmetrical half of curve D 1 until they go back to the same speed as the conveyors with thrusters and the rotating pincer-holding disc.
  • the motor 23 decelerates determining a deceleration of the two rollers 21 and carrying out a correct positioning of the individual sheeted product 10 in front of the thrusters 14 in arrival and then accelerates and goes back to the current operating speed of the packager V 3 .
  • the process according to the invention is particularly simple in structure and does not require complicated arrangements of constructive parts.
  • the materials used, as well as their sizes and the components of the feeder can be whatever according to the technical requirements.
